A debugging tool developed by researchers at Columbia and Lehigh generates real-world test images meant to expose logic errors in deep neural networks. The darkened photo at right tricked one set of neurons into telling the car to turn into the guardrail. After catching the mistake, the tool retrains the network to fix the bug.

Researchers at Columbia and Lehigh universities have come up with a new approach to self-driving cars and other self-taught systems.
The four winners of the MacArthur Genius Grant 2017.
Urban Design Program Director Kate Orff and Architecture Adjunct Damon Rich won 2017 MacArthur Foundation "genius" grants. Musician Tyshawn Sorey and Computer Scientist Regina Barzilay, both Columbia alumni, were also named MacArthur Fellows.

Digital technology is about to add big data to the bird enthusiast’s traditional tools of binoculars and a field guide.

Shree Nayar has dedicated much of his computer science career to improving the way cameras take pictures. Four years ago, he decided to move in a new direction: to design a camera that could improve the way children learn about science and one another. 

Joseph Traub (GSAS'59) was honored for his contributions to computer science.

When Joseph Traub joined Columbia’s Engineering School in 1979, it had a single computer, only three tenured faculty members teaching computer science and huge demand for the classes—but no computer science department.

Maybe you have heard of robots that can fly. But how about a robot that is able to learn through its own experiences to drive itself to the airport?
